GraphQL AccessALPHA

Access Sales Tax Lookup through GraphQL to combine it with other API calls in a single request. Query only the sales tax lookup data you need with precise field selection, and orchestrate complex data fetching workflows.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

POST https://api.apiverve.com/v1/graphql

query {
  salestax(
    input: {
      zip: "64082"
    }
  ) {
    state
    zip
    region
    rate
    county
    city
    special
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Sales Tax Lookup API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Sales Tax Lookup directly from browser-based applications without proxy servers.

Browser Usage: You can call Sales Tax Lookup directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

Sales Tax Lookup API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Sales Tax Lookup users.

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each Sales Tax Lookup response includes headers to help you track your usage:

Handling Rate Limits

Free Plan: When you exceed your rate limit, Sales Tax Lookup returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.

Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.

Best Practices for Sales Tax Lookup:

• Monitor the rate limit headers to track your Sales Tax Lookup usage (Free plan only)
• Cache sales tax lookup responses where appropriate to reduce API calls
• Upgrade to Pro or Mega for guaranteed no-throttle Sales Tax Lookup performance

Note: Sales Tax Lookup rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Sales Tax Lookup on Free tier.

Error Codes

The Sales Tax Lookup API uses standard HTTP status codes to indicate success or failure:
